NONRE'FILLABLE BOTTLE Application filed August 3, 1929. Serial No.383,372.

The object of this invention is the provision of a bottle neckconstruction and means there-v in which will permit of the fluidcontents of the bottle being freely poured therefrom, but a which, afterthe contents'have been poured therefrom will positively prevent therefilling of the bottle by any means or regardless of any angle whichthe bottle is caused to assume.

To the attainment of the foregoing the invention consists in theimprovement hereinafter described and definitely claimed.

Before proceeding with a detailed description of the improvement Idesire to have it understood that the construction of the componentparts constituting the invention requires no departure from the presentday glass manufacturing methods. The bottle can he hlown in theusual-manner by simply adding a neck-mold to the blow pipe. The othercomponent parts can be readily blown or molded from glass. The onlyincrease in cost would be that necessary in making the original molds,(which would be negligible in the end considering the number that couldbe produced from one mold), and the additional small amount of glassnecessary to make the parts. It will be noted as the descriptionprogresses that no complicated work will be involved in inserting theparts and the cap ing of the bottle, as there is no matching 0 the partsrequirin painstaking hand operations before or during the insertionthereof and the capping of the bottle. Also in this connection it may bewell to state that bottling machinery can be adapted to the handling ofthe improvement for a quantity production basis which is essential incutting down the production costs.

In the drawings I have not deemed it necessary to illustrate a completebottle, but the neck 1 thereof is blown in three steps to accommodatethe inserted parts. The first step which comprises a flat seat tocontact with the under face of the valve which will presently bedescribed. The seat is surrounded by a groove 2, and the inner wall ofthis groove is cut at an inward angle. The second step 3, which isslightlyabove the step or valve seat 1 accommodates the cap 4: which isarranged directly over the valve and the third step 5 accommodates thesealing lug 6. Above the step 5 the neck of the bottle is formed with anannular groove 7 for. the reception of a split spring wire or member 8received in the peripheral groove in the sealing plug 4 which expandsand enters the said groove 7 for holding the sealing valve in the bottleneck. In

addition to this the sealing plug has an upper peripheral groove for thereception of a packing 8 and a lower annular groove for the reception ofa packing 9 that rests directly on the step or shoulder 5.

The valve 10 is in the nature of a flat disc .with a rojecting lug 11that is equal tothe circum erential measurement of two fins 12 formed onthe periphery of the cap 4. The lower or bottom face of the valve 10 isflat so that the same will effectively rest on the seat 1. The valve isof such diameter in relation to the seat 1 as to cover the said seat inany position of its free movement under the cap 4 and within the annulargroove or depression between the valve seat and the shoulder 3, whichspace affords a guide race for the valve. On aline through the center ofthe disc valve 10 and the projecting lug 11 there is formed on the underface of the said valve a stem 12. This stein has on its outer end a ballhead 13 ,to weight the said stem. The stem is of a form bevel 14 so thatthe valve is held tight (ill under the fins 12 of the cap 4.

The valve ap 4 is cylindrical in shape and, as stated, ha its outerperiphery fluted to allow passage of the bottled contents. The topsurface of the valve cap has an upstanding annular lip 15 to prevent theinsertion of any article through the sealing plug 6 which otherwisemight pass through the sealing plug, through the flutes of the bottle toengage with the bottle for holding the latter open. The bottom of theflutes or fins 12 are flat for contacting with the step 3 in the bottleneck and also to act as retaining blocks for the valve 10. The valve capserves as a guide and also a lock for the valve; 10. From its bottom thecap 4 is formed with a cup-like recess or depression 16, the bottomofthe cap proper being disposed above the lower ends of the flutes 12and the diameter of this recess or depression is such as to provide aclearance for the flapper action of the valve 10. The bottom surface ofthe fins 12 retains the lug of the valve under them and against'the wall17 that provides the outer wall of the depression 2 and which I havereferred to as the guideway. This contact of the lug 11 with the wall orguide race 17 allows the valve 10 to swing upwardly, on the fulcrumaifordedbetween the guide seat 1 and the depression 2 when the bottle istilted to empty the contents therefrom. As long as the bottle is incorrect position for em tying the valve 10 remains concentric with t 1evalve cap recess'and works freely. WVhen the bottle is empty and noweight is behind the valve the stem with its extended center of gravitycauses the valve lug to engage one or two' fins and, through gravityaction, the fins act as a block and the weight of the stem 12 and ball13 exerts a downward pulling upon the valve '10 and keeps the said valveagainst its seat. This takes place in the proper emptying position. fr

The "alve stem being attached eccentric to the disc valve has a tendencyto cause the said valve to move in the guide race to find its lowestpoint of gravity.

Figure 8 discloses the relation between the disc valve and the valve cawhen the disc lug engages two fins while t e bottle is held with valvein proper emptying position. The disc valve is concentric with the finsof the valve cap and the disc lug is engaging fins on bottomto allow thelug 11 to serve as a fulcrum against the seat 1 so that the valve canenter the depression orrecess 16 to permit of the discharge of thecontents of the bottle. However, should the valve not be opened,provision has been made to prevent the valve acting in any otherposition. The

disc valve can only enter the recess or depression 16 when the saidvalve is concentric with the said recess or depression. Should the edgeof the valve disc touch the gmde race or. wall 17 atany point other thanthat engaged by the lug 11 the said disc loses its concentricity withthe valve cap' recess and engages a number of fins that retain it in aclosed position. This prevents gravity action of the stem and ball endof the valve from working in a reverse direction to open the valve. Inthis position the bottle cannot be filled and discharges its contentsslowly, if at all, depending on the body of the contents. This is bestillustrated by Figure 9 of the drawings which shows the disc valve inthe extreme eccentric position with respect to the valve cap fins. Thisfigure also shows the disc valve engaged by a number of fins to retainit in closed position. It is at this point. that the value of thebeveled outer edge of thetop surface of the valve is seen and, it isthought appreciated. This beveled edge causes easy entrance of the valveunder the finsat any position and also makes a snug fit under the finsby gravity pressure. The sealing plug 6 is provided with a centralsomewhat restricted outlet opening 18 arranged above the flange 15 onthe cap and with an annular depression 19 upon its lower face in whichthe flange 15 of the cap is received, and there is a comparativelynarrow passage between the said depression or recess 19 and the lip 15of the cap. .It is also to be noted that the lower end of the sealingplug rests directly over the fins 12 of the cap and further that Iemploy no Wax or similar sealing means for sealing the plug in thebottle neck.

It will be noted from the above description when carefully read that Ihave produced a simple, cheaply constructed bottle construction whichwill freely permit of the passage of the fluid contents from the bottlebut which will eflectively'and positively prevent the refilling of thebottle afterthe original contents have been poured thereom. It will befurther noted that the parts constituting the improvement may be cheaplyconstructed in quantities and it is to be imderstood that while I haveherein illustrated a satisfactory embodiment my features of inallvention are capable of extended application and I do not wish to belimited to the specific structure herein shown and described.

it is to be noted that the lower wall provided by the groove 7 for thepacking or holding ring 8 is beveled or chamfered so that the expansiblering 8 can be fully received in the groove when the plug is inserted inthe bottle neck and thereby materially facilitate such insertion of theplug. in addition to this any attempt to withdraw the plug from thebottle neck will cause the split holding ring 8 to travelover theinclined wall provided by the chamfer to further expand the same and tobring the said ring into tighter engagement with the groove provided inthe bottle neck for the reception thereof.
